Fast blue salt B is a diazonium salt which has been recommended as a coupling agent in a technique which demonstrates aldehydes. 2-hydroxy-3-naphthoic hydrazine is applied to sections in which aldehydes have been generated by some means. The resulting complex then reacts with fast blue salt B forming a blue violet azo dye.

Do not confuse with the textile dye fast blue B (CI 63010, acid blue 45).
